I recently made plans to get into vinyl some day, and I was looking into the bugle phonostage, and I ended up making a BOM.
Well, seeing as it's only ~$30, I think am going to go ahead and build one..
My mother has a turntable that hopefully works (I'll probably check that it works before ordering), and I figure I'll want one soon or later anway.
I've spent too much time on this now not to go ahead and build it =p
anyway, here is the mouser BOM.
There are two listings that are digikey part numbers, because I have these parts left over from a CMOY order.
I am building it on a protoboard, the same one the CMOY uses. I think it'll fit, but I might have to get creative with some of the capacitors.
The stock BOM, schematic are here:

Now for the questions:

- There isn't any reason I can't use that 470uF from the CMOY build in place of the 220uF, is there? (C7/C10)
- I am not really sure what C8/C11 does. My friend says switch bounce.. which may be relevant in this really low noise type device? I am using a capacitor very similar to the stock here, are there any recommendations?
- I need some RCA jacks for both my bantam and this, any recommendations?
- OPA2132's are expensive, is there anything else you guys can recommend I could use? I think there might be some threads about this one, but information is really disorganized.. Might have to take another look.
- Any inexpensive switch recommendations?
- any other thoughts?
Maybe Cardas CTFA at ~$6.25 apiece, or possibly the connex line at partsconnexion. They are having a 20% off sale until Friday. The Daytons at partsexpress are another option:
